TECHNICAL FIELD

The present invention relates to a melting furnace capable of processing various waste materials through thermal decomposition.

BACKGROUND ART

In recent years, as industry has been developed and the standard of living has been improved, various types of waste materials have rapidly increased, and thus, attention has focused on methods of processing waste materials. As the methods of processing the waste materials, there are a method of reducing the amount of waste materials generated, a method of recycling the generated waste materials, and a method of burning or burying waste materials that cannot be recycled. In the case of domestic waste materials, most waste materials have been buried. As the method of burning the waste materials, a direct incineration method has been widely used.

However, in the direct incineration method, there is a demerit that deadly harmful poison materials such as dioxin or furan which are magnified as serious environment problems are generated after the waste materials are burned. Accordingly, since facilities for processing harmful materials are further provided, the burden may grow heavier. Further, since energy obtained by burning fossil fuel such as light fuel oil as an external heat source for burning the waste materials is independently used, resources may be wasted.

Disclosure Technical Problem

An object of the present invention is to provide a melting furnace using anion oxygen by which it is possible to thermally decomposing all waste materials without polluting and it is possible to recycle decomposed material remaining after the decomposition.

Technical Solution

In order to achieve such an object, the present invention provides a melting furnace using anion oxygen including a furnace main body that includes an internal space, is provided with a waste injection hole and a decomposed gas discharge hole on the top surface, and is provided with at least one ash discharge hole on the side surface; an injection hole door that opens and closes the waste injection hole; a discharge hole door that opens and closes the ash discharge hole; a dust collector that is provided at the decomposed gas discharge hole, and collects ash included in the decomposed gas within the furnace main body; a punched plate that is disposed so as to be apart from the bottom within the furnace main body, and is provided with a plurality of vent holes which vertically penetrate the punched plate; and an anion oxygen supply unit that supplies magnetized anion oxygen to the upper region of the punched plate positioned within the furnace main body.

EFFECT OF THE INVENTION

According to the present invention, since the waste materials are naturally decomposed due to the high-temperature radiant heat using the anion oxygen, it is possible to process the waste materials environmentally friendly unlike the direct incineration type of the related art. After the charcoal is ignited, since the waste materials are thermally decomposed without independently supplying an additional heat source into the furnace main body, it is possible to save energy. The mineralized ceramic minerals can be used for industries, and since the ash collected through the dust collector can be used for the purpose of sterilization, insecticide or fertilizer, it is possible to obtain an effect of recycling resources.

Referring to FIGS. 1 to 3, a melting furnace 100 using anion oxygen includes a furnace main body 110, an injection hole door 120, a discharge hole door 130, a dust collector 140, a punched plate 150, and an anion oxygen supply unit 160.

The furnace main body 110 has an internal space. For example, the furnace main body 110 may have a rectangular-parallelepiped chamber shape having an internal space. A thermal decomposition process is performed in the internal space of the furnace main body 110. A waste injection hole 111 and a decomposed gas discharge hole 112 are formed in the top surface of the furnace main body 110. At least one an ash discharge hole 113 is formed in the side surface of the furnace main body 110. For example, the ash discharge holes 113 may be respectively formed in both side surfaces of the furnace main body 110. A foot board 114 may be provided at the center of the side surface of the furnace main body 110 to allow an operator to stand thereon.

The furnace main body 110 may have a double partition structure having an inner wall 115 a and an outer wall 115 b. A partitioned space limited by the inner wall 115 a and the outer wall 115 b may be filled with a heating medium, for example, water. The water in the partitioned space may be heated with heat generated during the thermal decomposition of waste materials in the furnace main body 110, and may be used as hot water, or may be used for heating or generating power. In this case, pipes for supplying or discharging water into or from the partitioned space may be provided. As another example, the partitioned space may be filled with a heat insulating material.

The injection hole door 120 opens and closes the waste injection hole 111. When the injection hole door 120 is opened, the waste materials may be injected into the furnace main body 110 through the opened waste injection hole 111. The injection hole door 120 may be coupled to the top surface of the furnace main body 110 through a hinge so as to be vertically rotated. The injection hole door 120 may be locked by a locking unit 121 while the waste injection hole 111 is closed.

The locking unit 121 may include a locking lever 122 that is rotatably coupled to the furnace main body 110, and a pushing block 123 that is coupled to the locking lever 122. The pushing block 123 operates to fix or unfix the injection hole door 120 with the rotation operation of the locking lever 122. A shock absorber 124 may be provided between the injection hole door 120 and the furnace main body 110, and can absorb shock when the injection hole door 120 is opened or closed.

The discharge hole door 130 opens or closes the ash discharge hole 113. When the discharge hole door 130 is opened, the decomposed ash from the waste materials may be discharged through the opened ash discharge hole 113. The discharge hole door 130 may be coupled to the side surface of the furnace main body 110 through a hinge so as to be vertically rotated. The discharge hole door 130 may be locked by the locking unit 131 of a handle type while the ash discharge hole 113 is closed. A thermometer for measuring the temperature within the furnace main body 110 may be provided at the discharge hole door 130.

The dust collector 140 is provided at the decomposed gas discharge hole 112. The dust collector 140 collects ash included in the decomposed gas within the furnace main body 110. That is, the dust collector 140 purifies the decomposed gas generated during the thermal composition of the waste materials, and discharges the purified gas. Meanwhile, the dust collector collects the ash included in the decomposed gas. A mesh net for filtering may be provided at a portion of the decomposed gas discharge hole 112 to which the decomposed gas is introduced.

The punched plate 150 is disposed so as to be apart from the bottom surface within the furnace main body 110. A lower space 116 of the punched plate 150 may function as a space where charcoal is placed. Here, the charcoal may be used for ignition, may be used to remove moisture within the furnace main body 110 when the melting furnace 110 is initially used, or may used to remove moisture of the waste materials injected into the furnace main body 110. Rice straw or the like may be used instead of the charcoal. The lower space 116 of the punched plate 150 may be communicatively connected to the outside through a ventilation pipe 117 provided from the outside of the furnace main body 110. The ventilation pipe 117 may used to supply air into the lower space 116 of the punched plate 150 or clean the lower space 116 of the punched plate 150 after the thermal decomposition of the waste materials is finished.

A ceramic layer may be disposed on the top surface of the punched plate 150. The ceramic layer may generate far-infrared radiant energy by receiving heat generated during the burning of the charcoal, and may supply the generated far-infrared radiant energy to the waste materials. Further, the ceramic layer may generate far-infrared radiant energy by receiving heat generated during the thermal decomposition of the waste materials, and may resupply the generated far-infrared radiant energy to the waste materials. Accordingly, the thermal decomposition of the waste materials may be prompted. The ceramic layer may be made of ceramic in the form of powder or may be made by reusing ceramic ash that is thermally decomposed in the melting furnace 100. The ceramic layer may be omitted.

The punched plate 150 has a structure in which a plurality of vent holes is formed in a plate-shaped member so as to vertically penetrate the plate-shaped member. The vent holes allow the lower space 116 of the punched plate 150 to be communicatively connected to the upper space of the furnace main body 110 positioned on the upper side of the punched plate 150.

For example, the vent holes may include first vent holes 151, and second vent holes 152. The first vent holes 151 may be greater than the second vent holes 152 in size, and may be arranged at the center of the punched plate 150 with a predetermined interval. The second vent holes 152 may be arranged between the edge of the punched plate 150 and the first vent holes 151 with a predetermined interval.

The first vent holes 151 allow the ignited charcoal to be placed in the lower space 116 of the punched plate 150. Furthermore, the flame generated during the burning of the charcoal may heat the ceramic plates by reaching the ceramic plates through the first vent holes 151. Since the second vent holes 152 allow air to permeate between the charcoal and the waste materials, the moisture of the waste materials can be removed by the charcoal, and it is possible to supply oxygen for burning the charcoal.

The anion oxygen supply unit 160 supplies magnetized anion oxygen to the upper region of the punched plate 150 positioned within the furnace main body 110, for example, the upper region of the ceramic layer. In this case, the magnetized anion oxygen has magnetization energy. The anion oxygen having the magnetization energy generates radiant energy by causing the furnace main body 110 to enter a reduced state. The radiant energy prompts the molecular motion of the waste materials, and thus, the waste materials generate heat by themselves. Accordingly, the waste materials may be dried through self-heating. The dried waste materials are carbonized by being thermally decomposed, and may be ultimately mineralized.

Operation examples of the melting furnace 100 having the configuration described above will be described below.

Firstly, a material for ignition and removing moisture such as charcoal is ignited, and is injected into the furnace main body 110. Thereafter, the ceramic layer may be formed on the top surface of the punched plate 150 when necessary. Subsequently, the waste materials are injected into the furnace main body 110 through the waste injection hole 111, and the waste injection hole 111 is closed by the injection hole door 120.

By doing this, heat generated during the burning of the charcoal is transferred to the ceramic layer, and far-infrared radiant energy is generated and is transferred to the waste materials. In addition, magnetized anion oxygen is supplied to the waste materials within the furnace main body 110 by the anion oxygen supply unit 160. Thus, the anion oxygen having the magnetization energy generates radiant energy by causing the furnace main body 110 to enter a reduced state. The radiant energy prompts the molecular motion of the waste materials, and thus, the waste materials generate heat by themselves. Accordingly, the lower portions of the waste materials placed in the region to which the anion oxygen is supplied are dried through self-heating, and are thermally decomposed. Accordingly, a carbonization layer is formed.

Radiant heat having a high temperature of 400° C. is generated in the carbonization layer. The carbonization layer is naturally decomposed by the high-temperature radiant heat, and is mineralized as ceramic minerals in the form of ash. In this case, the mineralized portions of the waste materials are reduced in volume, and the ceramic layer is formed by the ceramic minerals. The upper portions of the mineralized portions are dried by the radiant heat, and are moved to the region where the anion oxygen is supplied. Thereafter, the moved portions are carbonized and mineralized in the aforementioned process. By repeatedly performing this process, all of the waste materials may be mineralized. The ceramic minerals mineralized in the form of ash may be discharged through the ash discharge hole 113 opened by the discharge hole door 130.

As described above, since the waste materials are naturally decomposed due to the high-temperature radiant heat using the anion oxygen, a very small amount of harmful toxic materials may be generated unlike the direct incineration type of the related art in which harmful toxic materials such as dioxins are generated due to incomplete combustion. Since the decomposed gas including the very small amount of harmful toxic materials can be purified in a level capable of satisfying a standard of natural environment by passing through the dust collector 140 and can be discharged into air, it is possible to process the waste materials environmentally friendly.

After the charcoal is ignited, since the waste materials are thermally decomposed without independently supplying an additional heat source into the furnace main body 110, it is possible to obtain an energy saving effect. Since the mineralized ceramic minerals can be used for industries, it is possible to obtain an effect of recycling resources.

Meanwhile, the decomposed gas generated during the thermal decomposition within the furnace main body 110 passes through the dust collector 140. The dust collector 140 purifies the decomposed gas, discharges the purified gas, and collects the ash included in the decomposed gas. Here, the collected ash is a mineral having an effect such as sterilization or fertilizer, and may be used for the purpose of sterilization, insecticide or fertilizer.

The anion oxygen supply unit 160 may include various components. As one example, the anion oxygen supply unit 160 may include first supply pipes 161, second supply pipes 162, magnetizers 163, and valves 164. Both ends of the first supply pipes 161 are open. One ends of the first supply pipes 161 are provided by penetrating the furnace main body 110 along the circumference of the furnace main body 110. The one ends of the first supply pipes 161 which have penetrated the furnace main body 110 are arranged adjacent to the edge within the furnace main body 110, and may supply the magnetized anion oxygen to the edge of the waste materials within the furnace main body 110. The first supply pipes 161 may be vertically arranged in double columns along the circumference of the furnace main body 110.

Both ends of the second supply pipes 162 are open. One ends of the second supply pipes 162 are provided by penetrating through the furnace main body 110. The one ends of the second supply pipes 162 which have penetrated the furnace main body 110 are arranged closer to the center of the furnace main body 110 than the end ends of the first supply pipes 161, and may smoothly supply the magnetized anion oxygen to the center of the waste materials within the furnace main body 110. Although it has been described that two second supply pipe 162 are used, one second supply pipe or three or more second supply pipes may be used.

The magnetizers are respectively provided at the first supply pipes 163. The magnetizers 163 may be provided so as to respectively surround the circumferences of the first supply pipes 161. The magnetizers 163 magnetize external air passing through the internal spaces of the first supply pipes 161, and generate the magnetized anion oxygen. The magnetizers 163 may include permanent magnets. The permanent magnets have the arrangement and magnetic force capable of generating the anion oxygen by magnetizing external air passing through the internal spaces of the first supply pipes 161, and may be arranged at the circumference of the first supply pipes 161. In this manner, the magnetizers 163 are respectively provided at the second supply pipes 162, and magnetize external air passing through the internal spaces of the second supply pipes 162 to generate the magnetized anion oxygen.

The valves 164 are respectively provided at the first and second supply pipes 161 and 162. The valves 164 adjust the flow rate of the magnetized anion oxygen supplied to the furnace main body 110 through the first and second supply pipes 161 and 162. The magnetized anion oxygen is naturally introduced into the furnace main body 110 through the first and second supply pipes 161 and 162 during the thermal decomposition of the waste materials and the burning of the charcoal within the furnace main body 110, and the magnetized anion oxygen may be supplied or may not be supplied into the furnace main body 110 through the first and second supply pipes 161 and 162 depending on whether the valves 164 are opened or closed. Moreover, by adjusting the opening degrees of the valves 164, the flow rate of the magnetized anion oxygen that is supplied to the furnace main body 110 through the first and second supply pipes 161 and 162 may be adjusted.

The dust collector 140 may includes a first dust collecting unit 141, and a second dust collecting unit 146.

Referring to FIG. 4, the first dust collecting unit 141 receives cyclic water by a pump or the like, and discharges the received water through a first discharge hole 142 a. The first dust collecting unit 141 spays the cyclic water to the decomposed gas supplied through the decomposed gas discharge hole 112. For example, the first dust collecting unit 141 may include a nozzle pipe body 143 including a plurality of nozzles. The nozzle pipe body 143 may receive the cyclic water sent from the pump, and may spray the cyclic water to the decomposed gas within the first dust collecting unit 141 through the nozzles.

The first dust collecting unit 141 collects the separated ash floating on the internal cyclic water through a first collecting hole 142 b positioned higher than the first discharge hole 142 a by spraying the cyclic water to the decomposed gas, and exhausts the remaining decomposed gas.

That is, the ash included in the decomposed gas and the cyclic water fall to the lower side of the first dust collecting unit 141, and the separated ash floats on the internal cyclic water within the first dust collecting unit 141. The internal cyclic water of the first dust collecting unit 141 is discharged through the first discharge hole 142 a, and is sent to the first dust collecting unit 141 again by the pump. When the floated ash is raised up to the height of the first collecting hole 142 b positioned higher than the first discharge hole 142 a, the floated ash is collected to a collecting tank (not shown) through the first collecting hole 142 b. The remaining decomposed gas within the first dust collecting unit 141 is discharged to the second dust collecting hole 146.

The second dust collecting unit 146 receives the cyclic water, and discharges the received cyclic water through the second discharge hole 147 a. The second dust collecting unit 146 sprays the cyclic water to the remaining decomposed gas supplied from the first dust collecting unit 141. In order to spray the cyclic water to the remaining decomposed gas, a nozzle pipe body 148 having a structure similar to the aforementioned structure may be used.

The second dust collecting unit 146 collects the separated ash floating on the internal cyclic water to the first dust collecting unit 141 through the second collecting hole 147 b positioned higher the second discharge hole 147 a by spraying the cyclic water to the remaining decomposed gas, and exhausts the remaining decomposed gas.

That is, the ash included in the remaining decomposed gas and the cyclic water fall to the lower side of the second dust collecting unit 146, and the separated ash floats on the internal cyclic water of the second dust collecting unit 146. The internal cyclic water of the second dust collecting unit 146 is discharged through the second discharge hole 147 a, and is sent to the second dust collecting unit 146 again by the pump. When the floated ash is raised up to the height of the second dust collecting hole 147 b positioned higher than the second discharge hole 147 a, the ash is collected to the first dust collecting unit 141 through the second collecting hole 147 b, and is collected together with the separated ash in the first dust collecting unit 141 to the collecting tank. The remaining decomposed gas within the second dust collecting unit 146 is exhausted.

As stated above, since the decomposed gas generated within the furnace main body 110 passes through the first and second dust collecting units 141 and 146, the ash included in the decomposed gas within the furnace main body 110 may be collected by being filtered as much as possible. The gas from which the ash has been filtered may be purified in a level capable of satisfying a standard of nature environment, and may be discharged into air.

In order to further purify the remaining decomposed gas exhausted from the second dust collecting unit 146, one or more additional dust collecting units 149 may be provided, as shown in FIG. 1. In the same manner as that in the first and second dust collecting units 141 and 146, the additional dust collecting unit 149 may separate the ash from the decomposed gas, and may remove the separated ash. The additional dust collecting unit may further include filtering means such as a filtering material.
